What is the standard of tinplate box?

Standards For Tinplate Boxes

Tinplate Boxes, Also Known As Tin Cans Or Tin Boxes, Are Packaging Containers Made From Tinplate. The Standards For Tinplate Boxes Vary Based On Different Specifications And Manufacturing Processes. Here Is A Comprehensive Guide To The Standards And Requirements For Tinplate Boxes.

Material Thickness Standard

The Thickness Of The Tinplate Material Used For Boxes Varies Depending On The Specifications And Processes. Typically, The Thickness Of The Tinplate Used By Our Company Ranges From 0.23mm To 0.38mm. The Thickness Is Determined By The Size Of The Box. For Instance, Drawing Boxes Require A Higher Thickness Of Tin Because The Drawing Process Thins The Tin. If The Tin Is Too Thin, It May Tear During The Drawing Process, Leading To Box Scrap.

Performance Characteristics

1. Excellent Barrier Properties**: Metal Packaging Materials Have Extremely Low Permeability To Gases And Water, Good Aroma Retention, And Are Completely Opaque, Effectively Avoiding The Harmful Effects Of Ultraviolet Light. Their Barrier Properties Against Gases, Moisture, Light, And Aroma Retention Far Exceed Those Of Other Packaging Materials Such As Plastic And Paper.

2. Good Ductility**: Metal Packaging Materials Have Good Ductility And High Strength, Allowing For Processes Such As Stamping, Rolling, Drawing, And Welding. They Can Be Made Into Thin-Walled, High-Pressure Resistant, And Durable Packaging Containers.

3. Metallic Luster And Good Decorative Properties**: The Special Metallic Luster, Combined With Exquisite Decorative Printing, Can Make The Product Appear Luxurious And Visually Appealing, Thereby Increasing The Product's Value.

The Manufacturing Standards For Tinplate Boxes Include Several Key Aspects:

1. Welding And Coating Inspection Standards**: The Welding Seams Of Round Tin Cans Should Be Smooth And Uniform, Completely Covering The Weld And Coating Gaps. The Coating Should Be Fully Cured, Without Large Bubbles Or Exposed Iron Points. The Inner Wall Coating Of The Tin Box Should Not Peel Off, And There Should Be No Severe Sulfurization Spots Or Oxidation Rings.

2. Appearance Inspection Standards**: The Patterns And Text On Round Tin Boxes Should Be Consistent With The Sample, Without Overprinting Or Underprinting. The Patterns And Text Should Be Accurately Aligned, With A Maximum Misalignment Of 0.5mm. The Body Of The Tin Box Should Not Have Edges Or Burrs, And The Surface Patterns And Text Should Not Have Severe Scratches Or Abrasions.

3. Material Inspection**: The Material For Round Tin Cans Is Tin-Coated Thin Steel Plate, And The Content And Specifications Of The Tin Coating Should Meet The Quality Requirements Of The National Standard For Tin-Coated Thin Steel Plates (Gb2520).

4. Shape Inspection Standards**: The Edges Of Round Tin Cans Should Not Have Sharp Edges, False Rolls, Or Large Collapses. There Should Be No Incomplete Rolling, Rolling Teeth, Iron Tongues, Jumping Seals, Rolling Fractures, Filler Extrusion, Sharp Edges, Hanging Lips, Double Lines, Or Other Defects Caused By Press Head And Metal Can Rolling Wheel Failures. The Tin Layer On The Edges And Sealing Edges Of The Round Tin Box Should Be Complete, Without Piled Tin Or Rough Tin Paths, And There Should Be No Obvious Scratches Or Rust On The Tin Can, No Sand Holes Or Other Leakage Phenomena, And The Shape Of The Tin Can Should Be Complete, Without Dented Cans Or Sharp Corners.

Conclusion

The Standards For Tinplate Boxes Are Crucial For Ensuring The Quality And Functionality Of The Packaging. These Standards Cover Material Thickness, Performance Characteristics, And Manufacturing Processes, Ensuring That Tinplate Boxes Meet The Requirements For Various Applications. By Adhering To These Standards, Manufacturers Can Produce High-Quality Tinplate Boxes That Protect And Enhance The Products They Contain.
